[IEC-103 Master Session 0 Sector 1]
Common ASDU Address : 1 #Range 0 to 255 Sector address
#Req init requests when session first online (not req if slave sends
# EOI sequence)
Online Time sync : Y #Send time sync message when first online
Online General Int : Y #Send general interrogation
#Req init requests when EOI (end of initialization) received from slave
EOI Time sync : Y #Send time sync message when first online
EOI General Int : Y #Send general interrogation
# Database definition for this session/sector
# Types are as follows:
#
# Monitored ASDU Types
# 1 = Time-tagged message (bit addressed with 2 bits/point)
# 2 = Time-tagged message with relative time (bit addressed with 2 bits/point)
# 3 = Measurands I (4 word values using word address using double-word address)
# 4 = Time-tagged measurands with relative time (1 float value)
# 5 = Identification (12 characters using a byte address)
# 9 = Measurands II (9 word values using word address)
#
# Point Index is the information object number in the slave unit.
# ASDU Index Description
# 1 Bit address with each point occupying 2 bits
# 2 Bit address with each point occupying 2 bits
# 3 Word address with each point occupying 4 words
# 4 Double-word address for the single float value
# 5 Byte address with each point occupying 12 bytes
# 9 Word address with each point occupying 9 words
